That is one possible explanation, but then the question implies that murder was committed but that no one can accuse him of it. The other reason why he might never be formally accused or convicted of the crime would be if he immediately killed himself afterwards, or if the police (or someone else) killed him at the scene of the crime. A dead person cannot stand trial, or be formally accused of a crime by the police.

Aaryan was walking in the park when he saw his friend, Danish. He saw that Danish had his eyes closed. Aaryan asked Danish if he was OK and Danish said he was very tired because he had carried a tree for five miles. Aaryan told Danish he was either a liar or completely mad! However, Danish was able to prove he did, in fact, carry a tree for five miles. How was that possible?

You are living at you place alone. You own a shed which has been locked. The lock that has been placed on the door can be closed without a key but need the key to be opened. You collected some old stuff and decided to keep it in the shed. After keeping the things, you locked it back. The next day, the police found a dead body inside the shed. As you are the only one living in your house, the police has nothing else to believe than you are the murderer. But you have not committed any crime.

There is a way the murder would have happened. Can you find that way and tell the police so you are not sentenced for the crime you did not commit?

A truck driver is on the job hauling wood across the state. Unbeknownst to him, his neighbor stuffed a potato in the exhaust pipe of his car the night before he started his haul. The truck driver makes it to his destination with no break downs or any damage to his vehicle. How is this possible?
